Abstract :
We have presented a numerical investigation of a wideband coaxial-based helical antenna for deep-seated cancer treatment. The proposed antenna with a diameter of 1.79mm and the total length of 20mm, which is thin and small enough for invasive cancer treatment. Numerical simulations indicate that the antenna exhibits an acceptable return loss (5.6dB) over a wide frequency range from 2.82 to 11 GHz. The electric field distributions are confined along the antenna axial. We are now in the process of fabricating and testing that this type of antenna in experiment to verify its suitability for deep-seated cancer treatment.
